2004 Cadillac SLS V8 Two Wheel Drive Automatic 74000 miles
I have a warning light that comes on when hooked up to one of those hand held code readers it says that it's an O2 sensor. Can't remember exactly what it says but it's supposed to be the downstream sensor. I purchased a new one and the light came back on again. I'm told that there can be a number of reasons that it keeps coming back on but I'm trying to find the most likely reason for this. Any assistance you can provide is greatly appreciated.
